    Lookup values in three columns, TRUE if they match another sheet (sumproduct?)

    Hi guys,

    I have 3 coloumns of data on 2 sheets.

    On the first sheet I would like to add a 4th saying TRUE if the row of data is replicated on the other sheet, false if it doesn't match anywhere on the other sheet.

    Attached is a basic example.

    Thanks in advance.

    Try:

    =SUMPRODUCT(--('Should be'!$A$3:$A$10=A3),--('Should be'!$B$3:$B$10=B3),--('Should be'!$C$3:$C$10=C3))>0
    Where there is a will there are many ways.

    That's great, I thought it was a SUMPRODUCT but I haven't really explored that function completely.

    It's really useful, thanks.
